Thus, the HY hydrogen bond, unlike the covalent XH bond, results mainly from electrostatic attraction. As we have seen, the model of an ideal gas assumes that the gas particles (molecules or atoms) have virtually no forces of attraction between them, are widely separated, and are constantly moving with high velocity and kinetic energy. Inter molecular forces are the attractions between molecules, which determine many of the physical properties of a substance. What is the Intermolecular Force Worksheet - Lab Report Worksheet: What is the Intermolecular Force? Also, the absence of intermolecular forces above the surface of a liquid results in surface tension, the development of a skin on the surface, which causes beading of liquid droplets and also allows light objects to rest on a liquid surface without sinking (e.g., water bugs). % [Hint: When the diver reaches the water, his displacement is y=-3.0 m (measured from the board), assuming that the downward direction is chosen as the negative direction.] 0000034909 00000 n Molecules (covalent) in solid and liquid phases. weakest intermolecular force that results from the constant motion of electrons; occurs in all molecules . The former is termed an intramolecular attraction while the latter is termed an intermolecular. 2 h 2 s h 2 o. I2 has stronger forces because it.

This will convert the solid to a liquid and if the thermal energy is great enough to a gas. The instantaneous unequal sharing of electrons causes rapid polarization and counter-polarization of the electron cloud in atoms and molecules which generate (very) short lived dipole moments. The bent shape of the molecules leads to gaps in the hydrogen bonding network of ice. H2Se H2S H2Po H2Te Chem128 Dr. Baxley Intermolecular Forces Worksheet Answers 1. Justify your answers. Ap chemistry topic 3.1 intermolecular force worksheet 1. 0000001064 00000 n b) They are very similar so the change given by the intermolecular forces of attraction is not significant enough to bring about a larger change of enthalpy. Activity. Predict the molecular shape of each of the following: a. H2S bent b. CCl4 tetrahedral c. SO2 bent (lone pair on S, two double bonds) d. BrF no shape d. PCl5 trigonal bipyramidal 2. Three obvious consequences of Equations \(\ref{Col}\) and \(\ref{Force}\) are: To complicate matters, molecules and atoms have a distribution \(\rho(\vec{r})\) that result from the 3D distribution of charges (both nuclei and especially electrons).
